How excavators, dozers, wheel loaders, skid steers, telehandlers and tractors are sized and valued, and what to check before you buy a used one.
Field guide
Inside the Heavy Equipment Market
Six categories account for most of the used construction equipment traded in the United States. Each one is sized, priced and inspected differently. This guide covers what the machines do and which figures matter when you compare listings.

Excavators
Tracked digging machines that swing a boom, stick and bucket through a full circle.
Compact models under about 10 metric tons handle utility trenching and residential work, while mid-size and heavy classes take on mass excavation, demolition and pipeline jobs. Hydraulic thumbs, couplers and specialty buckets extend what one machine can do.
Typical useTrenching, site excavation, demolition, material handling

Bulldozers
Track-type tractors with a front blade for pushing, grading and spreading material.
Dozers are sized by horsepower and operating weight. Low ground pressure (LGP) versions run wider tracks for soft ground, a common requirement in Florida and the Gulf Coast. Blade type, grade-control readiness and undercarriage wear drive much of a used dozer's value.
Typical useRough grading, clearing, fill spreading, finish grading

Wheel Loaders
Rubber-tired loaders built for stockpiling, truck loading and moving bulk material fast.
Bucket capacity, breakout force and tipping load define the class. Quick couplers let a loader switch between buckets and forks, which is why many used units are sold with both. Tire condition is a significant cost line on larger loaders.
Typical useLoading trucks, stockpiling aggregate, yard and plant work

Skid Steers
Compact loaders on wheels or tracks that run a wide range of hydraulic attachments.
Compact track loaders (CTLs) dominate the used market in wet or sandy regions because the tracks float on soft ground. Rated operating capacity, auxiliary hydraulic flow and the age of the tracks are the figures buyers compare most.
Telescopic-boom forklifts that place loads at height and reach across obstacles.
Rated by maximum lift capacity and lift height, telehandlers are a staple of commercial building, masonry and agricultural operations. Four-wheel steer and crab modes help on tight sites. Boom wear pads and chain condition are inspection priorities.
Typical usePlacing materials on structures, lifting pallets, farm handling

Tractors
Utility and row-crop tractors that power loaders, mowers and implements on and off the farm.
Contractors use utility tractors with loaders and box blades for finish work, while agricultural buyers look at PTO horsepower, hydraulic remotes and transmission type. Mechanical front-wheel drive (MFWD) is standard on most modern units.
Typical useLoader work, mowing, grading, implement power
Buyer knowledge
What Buyers Should Consider
Three questions that decide whether a used machine is a good buy, drawn from how experienced fleet managers evaluate equipment.
I
Evaluating used equipment condition
A used machine is a record of how it was operated and maintained. Start with the structure: look for cracked welds at the boom foot, loader arms and blade push frames, and for repairs that were painted over rather than documented.
On tracked machines, measure undercarriage wear on the links, bushings, sprockets and rollers. Undercarriage can represent a substantial share of the remaining life cost on a dozer or excavator, so a machine with fresh steel may justify a higher price than a cheaper unit that will need it soon.
On your checklist
Request the service history and any inspection report the seller holds
Check hydraulic cylinders for scoring, leaks and pitted rods
Run every function to operating temperature, not just a cold start
Confirm the serial plate matches the paperwork
II
Reviewing operating hours and specifications
Hour meters tell you how long the engine has run, not how hard. A 1,000-hour excavator from a demolition fleet can carry more wear than a 3,000-hour machine from a utility contractor. Read the hours together with the application, the owner history and the condition of wear items.
Specifications matter because they decide whether a machine fits your work. Operating weight affects trailer choice and permits. Lift capacity and lift height set what a telehandler can place. Bucket size, auxiliary hydraulic flow and cab configuration all change what the unit is worth to you.
On your checklist
Compare hours against the model year to judge annual utilization
Verify engine, transmission and emissions tier against the serial number
Note which attachments and couplers are included in the price
Ask whether any factory or dealer protection plan transfers to a buyer
III
Planning transport and delivery
Moving heavy equipment is a project of its own. Machines above roughly 80,000 pounds gross combined weight, or wider than 8 feet 6 inches, typically require oversize or overweight permits that vary by state. Dozers with wide LGP tracks and large wheel loaders often fall into this category.
Get a transport quote before you commit to a purchase, and confirm who is responsible for loading at the seller's yard. Many dealers coordinate carriers; others expect the buyer to arrange the haul. Delivery lead time and insurance in transit should be settled in writing.
On your checklist
Confirm the machine's shipping dimensions and weight from the manufacturer
Check permit requirements for every state on the route
Decide whether buckets, blades or booms must be removed for transport
Settle payment, title transfer and insurance terms before the truck arrives
From the dealer spotlight
Sixty machines, seven categories, one Florida yard.
From a 2020 Caterpillar D6 LGP with a six-way blade to a 146-hour John Deere 35G mini excavator, the Perry dealer's listings show what a working inventory of used iron looks like in late 2026.
